Description

The LP2981 is a 100 mA, fixed-output voltage regulator designed specifically to meet the requirements of battery-powered applications.Using an optimized VIP™ (Vertically Integrated PNP) process,the LP2981 delivers unequaled performance in all specifications critical to battery-powered designs:
Dropout Voltage. Typically 200 mV @ 100 mA load, and 7 mV @ 1 mA load.
Ground Pin Current. Typically 600 A @ 100 mA load, and 80 A @ 1 mA load.
Sleep Mode. Less than 1 A quiescent current when ON/OFF pin is pulled low.
Smallest Possible Size. SOT-23and micro SMD packages use an absolute minimum board space.
Precision Output. 0.75% tolerance output voltages available (A grade).
Eleven voltage options, from 2.5V to 5.0V, are available as standard products.
